1191940-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1191940-86-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,9,4 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1191940-86:
(9*1)+(8*1)+(7*9)+(6*1)+(5*9)+(4*4)+(3*0)+(2*8)+(1*6)=169
169 % 10 = 9
So 1191940-86-9 is a valid CAS Registry Number.

Tandem asymmetric aza-Darzens/ring-opening reactions: Dual functionality from the silane Lewis acid
Valdez, S. Corey,Leighton, James L.
, p. 14638 - 14639 (2009)
(Chemical Equation Presented) The addition of a stabilized sulfur ylide (generated by the rhodium-catalyzed reaction of Ph2S with ethyl diazoacetate) to N-acylhydrazones promoted by a chiral silane Lewis acid leads to the highly diastereo- and
